SINR stands for Signal-to-Interference-plus-Noise Ratio. It measures the quality of a wireless communication signal.
SINR is calculated by measuring the strength of the desired signal, interference, and noise in a communication channel.
A higher SINR value indicates better signal quality and less interference.
A good SINR value is typically above 20 dB, while a bad value is below 10 dB.
SINR is important in determining the...
Interference is the disruption of a signal caused by other signals or environmental factors.
Interference can be caused by electromagnetic interference (EMI) from nearby electronic devices.
Physical obstructions like buildings or trees can also cause interference.
Interference can result in poor signal quality or loss of signal altogether.
RSRP actual value is the Received Signal Reference Power, a measurement used in wireless communication to determine signal strength.
RSRP is measured in dBm (decibels per milliwatt)
It is used in LTE networks to determine the quality of the signal received by a device
A higher RSRP value indicates a stronger signal strength, while a lower value indicates a weaker signal
RSRP values typically range from -140 dBm to -44 dBm
